Unreasonable Request

I offered to run some CFD for Paul Breed of a simple "rocket like" geometry - a 8" by 8' tube.  I picked an arbitrary ogive nose cone and a bluff tail.

Here is the Mach number contour for the 150 m/s case.

The free stream conditions were:

M 0.468
p 27580. Pa
rho 0.376 kg/m^3
T 255.4 K
V 150.0 m/s
Drag 55.1 N

The calculated Cd is 0.40.   300 m/s and 600 m/s results to follow.

Super cool simulation. What software did you use for this?
